Hi, i have the mother board biostar tf8200 am+ and a phenom 9950 processor, and it won't let me change the cpu reference clock from the default 200mhz...is there any bios options or anything i need to do in order to enable changing this? i've tried almost all bioses, including one that a review site successfully overclocked with -_-. So...tell me what i need to do XD. Also, does anyone happen to know how nb temps are for overclocking for this mobo?
